- Photovoltaics
Background:
- Perovskite solar cells (PSCs) show rapid advancements in power conversion efficiency (PCE).
- Solution-processed perovskite films are cost-effective but often polycrystalline with defects.
- Defect passivation is critical for improving PSC performance.
Purpose of the Study:
- To investigate propylamine hydroiodide (PAI) as a defect passivation agent for PSCs.
- To enhance the efficiency and stability of perovskite solar cells through defect mitigation.
Main Methods:
- Utilized propylamine hydroiodide (PAI) for defect passivation in perovskite films.
- Fabricated n-i-p and p-i-n perovskite solar cell architectures.
- Characterized device performance, focusing on PCE and recombination suppression.
Main Results:
- PAI passivation reduced defects and suppressed non-radiative recombination.
- Achieved a certified efficiency of 21% for n-i-p PSCs.
- Demonstrated improved efficiency up to 23% for p-i-n PSCs by using PAI as a buried interface layer.
Conclusions:
